TRACON Pharmaceuticals, Inc.

Good day, ladies and gentlemen, and welcome to the TRACON Pharmaceutical Second Quarter 2023 Earnings Conference Call. At this time, all callers are in a listen-only mode. After the speaker's prepared remarks, we will conduct a question and answer session, and instructions will be given at that time. During today's call, we will be making certain forward-looking statements, including statements regarding expected timing of clinical trials and results of regulatory activities, financing opportunities, future expenses, and cash runway. Our development plans and strategy, and with the recovery of the award from our arbitration with IMAP, these statements are subject to various risks that are described in our filings made with the Securities and Exchange Commission, including our annual report on Form 10-K for the year ended December 31st, 2022, and subsequent quarterly reports on Form 10-Q. You are cautioned not to place undue reliance on these forward-looking statements, and unless required by applicable law, we disclaim any obligation to update such statements. Now, I would like to turn the call over to Dr. Charles Thur, President and CEO of Tracon Pharmaceuticals. Dr. Thur?

Good afternoon, and thank you for joining Tracon's second quarter 2023 financial results and business update call. I will begin with an update on our pipeline and then review our recent activities. Following that, Scott Brown, our Chief Financial Officer, will discuss our financial results for the three and six months ended June 30, 2023. Finally, we will conclude by taking your questions. I'll begin with an update on our continued progress with the ongoing NVSARC pivotal trial. In June, the Data Monitoring Committee reviewed interim safety and efficacy data for more than 80 patients equally randomized into cohort C of single-agent ENVA treatment or cohort D of ENVA given in combination with Yervoy. Patients in cohort C who had at least two on-study CT scans continued to demonstrate a double-digit objective response rate assessed by investigator and blinded independent central review. ENVA was generally well-tolerated without a single greater than grade two drug-related adverse event. The combination of ENVA with Your Voice did not demonstrate synergy when compared to single-agent ENVA treatment, and we therefore terminated enrollment in cohort D. This decision has resulted in a reduction in trial costs and acceleration of the timeline to final ENVA-SARC data. We expect full accrual of the 80 patients into cohort C of treatment with single-agent ENVA in the fourth quarter, and final data including duration of response by mid-2024. In addition, a protocol-mandated DMC review will be conducted and reported after the 46th patient treated with ENVA has completed a minimum of 12 weeks of efficacy evaluations. We expect the DMC review to occur this quarter as the ENVASARC trial has enrolled 180 patients to date, including 56 of the 80 expected patients in cohort C of single-agent ENVA treatment. This DMC review includes a futility threshold that has already been achieved based on responses seen to date. As a reminder, the primary endpoint in NVISARC is objective response rate by RESIST, confirmed by blinded independent central review with nine out of 80 objective responses or an 11.25% objective response rate defines the level response that satisfies the primary endpoint of the study. to statistically exceed the 4% objective response rate of Votrien, the only FDA-approved treatment for patients with refractory UPS or MFS. Therefore, a double-digit response rate at the time of interim analysis is meaningful, indicating that we are on track to achieve the primary endpoint of the study. Notably, Votrien is a drug with a black box warning for fatal liver toxicity. Our goal in NVA-SARC, therefore, is to demonstrate that NVA has the potential to be both safer and more efficacious than Votreant. Based on data from trials of other checkpoint inhibitors and refractory UPS or MFS, we are targeting a 15% response rate for single agent NVA. Furthermore, we plan to approach the FDA to discuss a BLA filing strategy as soon as we determine nine responses. As a reminder, We have received FAST-TRACK designation for ENVA in the sarcoma subtypes of UPS and MFS that have progressed on one or two prior lines of therapy, and received orphan drug designation in soft tissue sarcoma based on activity observed in ENVASARC. These designations provide important advantages that might expedite regulatory review and commercialization of ENVA. ENVASARC is designed to provide safety and efficacy data for the approval of ENVA in the refractory sarcoma subtypes of UPS and MFS. We also have a strategy for the approval of ENVA in frontline sarcoma. Based on expected synergy between ENVA and Urovoi, we licensed Y8001, a potential best-in-class CLA-4 antibody from U-Cure Biopharma in October of 2021, and began a Phase I-II clinical trial evaluating a triplet that included Y8001, ENVA, and doxorubicin chemotherapy for the treatment of frontline sarcoma. However, given the lack of synergy observed in ENVA-SARC between ENVA and the CTLA-4 antibody Yervoy and available data from patients treated with ENVA and Y8001, we have decided to end enrollment into the trial as originally designed. We now plan to initiate a modified trial of ENVA and doxorubicin in the frontline setting of common sarcoma subtypes, including UPS and MFS, following completion of enrollment in the pivotal ENVA-SARC trial. The goal of that modified trial will be to determine the subtypes of sarcoma that best respond to the combination of ENVA and doxorubicin. Assuming positive results in the ENVA-SARC pivotal trial and potential accelerated approval of ENVA, We expect the FDA will require a randomized trial to demonstrate a survival benefit. We now expect this potential phase three post-approval trial will compare single agent doxorubicin to doxorubicin with ENVA with progression-free survival as the endpoint. This trial would be expected to enroll patients with UPS and MFS as well as other sarcoma subtypes shown to respond to therapy with ENVA and doxorubicin. We expect to discuss the design of a frontline trial with the FDA at the time of our expected pre-BLA meeting to review the expected submission of data from ENVA SARC for potential accelerated approval of ENVA in refractory sarcoma. It is important to understand the sales potential in sarcoma with ENVA at parity pricing is not solely the forecasted $200 million in peak annual ENVA revenues anticipated following approval in refractory UPS and MFS. Our clinical development strategy is designed to create the opportunity for ENVA to broadly benefit patients with sarcoma in the frontline, adjuvant, and neoadjuvant settings by seeking supplemental BLA approvals. We will now turn to our DNA damage repair inhibitor, TRC-102, that is supported through a cooperative research and development agreement with the National Cancer Institute. The NCI is sponsoring an ongoing randomized Phase II trial assessing TRC-102 in Stage III non-squamous non-small cell lung cancer in combination with chemoradiation. The two-arm trial will enroll 78 patients to assess the benefit of adding TRC-102 to current standard of care treatment of pemetrexed, cisplat, and radiation therapy, followed by consolidated drivalumab maintenance treatment. The primary endpoint of the trial is progression-free survival, and the trial is designed to detect an improvement in PFS at one year from 56% to 75%. Nine sites are open for enrollment in the U.S., and final results are expected in 2025. Next, I will provide an update on the collection of our arbitration award from IMAP. On April 24th, we were informed the tribunal ruled in our favor for certain claims and rendered an award to TRACON in the aggregate amount of approximately $23 million. Among other findings, the tribunal declared the TJ4309 trial complete which entitled TRACON to $9 million and also awarded legal fees and costs to TRACON. In July, we collected $22 million from IMAP in satisfaction of the International Chamber of Commerce award to TRACON announced in April. $10.5 million of the collected amount was used to repay our litigation financing facility in full And net proceeds collected to date of $7.1 million are expected to fund the company's operations as currently planned into the first half of 2024. An additional $4.4 million of the arbitration award remains in a client trust account administered by our law firm at this time, the disbursement of which is predicated on discussions as to the amount of success-based deferred legal fees the firm is due. Following these discussions, disbursement of all or a portion of that amount is expected later this year. We expect to further extend our runway by securing non-dilutive capital through leveraging our CRO-independent product development platform that we believe positions us as one of the most efficient clinical development organizations. As an example of our efficiency, our fully burdened per patient cost for dosing patients in the NVISARC trial is less than $90,000 per patient. This compares favorably with typical zero bid estimates of $300,000 per patient that may be even more expensive if change order charges are considered. In addition, by managing all regulatory filings internally, we believe we significantly shorten trial duration by exhibiting the approval of protocol amendments and consent forms. We also emphasize quality. Through the use of a team of reliable site monitors who are highly experienced with relevant oncology response criteria, to ensure accurate data reporting. These attributes of our product development platform have been the basis for capital infusions from partners like Johnson & Johnson, who have collaborated with us to run trials of their drug candidates. Our current focus is to work with companies in one of two ways. First, by replacing a CERO to lower their anticipated costs, but still generate a substantial profit for TRACON. And two, to teach our operational capabilities to a company with an emerging pipeline who plan to conduct multiple trials. This offering would include our platform of advanced clinical trial management, data management, and safety reporting that will enable our collaborator to conduct trials at a cost of less than one-third of what they may otherwise pay to a CRO. Leveraging our cost-efficient CRO independent product development platform to generate non-due of capital for the end of this year is a top priority for the company. In that regard, please note the corrected press release And let me reiterate, we expect to generate non-due of capital before end of this year by leveraging our zero independent product development platform. At this time, Scott will provide an update on our financials.

Thank you, Charles, and good afternoon, everyone. Collaboration revenue was $9 million for the three and six months ended June 30, 2023, compared to zero for the comparable periods of 2022. The increase in revenue was from the pre-specified $9 million termination fee for the TJ4309 license in conjunction with the arbitration outcome. TRACON's research and development expenses were $3.5 million and $8.5 million for the three and six months ended June 30th, 2023, compared to $2.9 million and $5.9 million for the comparable periods of 2022. The increase was related to ENVA drug purchased in the first quarter of 2023 as well as higher enrollment in NBISARC. General and administrative expenses were $1.9 million and $4.3 million for the three and six months ended June 30, 2023, compared to $3.3 million and $9.8 million for the comparable periods of 2022. The decrease was due to lower legal expenses. We incurred a success fee of $4.4 million in the three and six months ended June 30, 2023, related to legal fees for the arbitration and collection of the award in July. As Charles mentioned, this amount remains in our client trust account administered by our law firm, the disbursement of which is predicated on discussions as to the amount of success-based deferred legal fees the firm is due. Following these discussions, disbursement of all or a portion of that amount is expected later this year. Our net loss was $6.3 million and $14.8 million for the three and six months ended June 30, 2023, compared to 6.2 million and 15.7 million for the comparable periods of 2022. We will record a gain of $13 million related to the collection of the arbitration award in the third quarter of this year. And had this been recognized in the three and six months ended June 30th, 2023, it would have resulted in net income of 6.7 million for the three month period and a net loss of 1.8 million in the six month period on a pro forma basis. Turning to the balance sheet, at June 30, 2023, our cash, cash equivalents, and restricted cash totaled $1.9 million, compared to $17.5 million at December 31, 2022. As Charles mentioned, we collected the arbitration award in July, and net proceeds to date are approximately $7.1 million, which had this been collected prior to June 30, 2023, would have resulted in ending cash of $9 million on a pro forma basis. With the award collected, we expect our current capital resources to fund the company into early 2024. With that, I will turn the call back over to Charles.
